CloudFlare Claims Most Activity from Tor Is Malicious
June 28, 2016
Different sources suggest varying levels of malicious activity on Tor. Tech Insider shared an article responding to recent claims about Tor made by CloudFlare. The article, entitled, Google Search has a secret feature that shouts animal noises at you, offers information about CloudFlare’s perspective and that of the Tor Project. CloudFlare reports most requests from Tor, 94 percent, are “malicious” and the Tor Project has responded by requesting evidence to justify the claim. Those involved in the Tor Project have a hunch the 94 percent figure stems from CloudFlare attributing the label of “malicious” to any IP address that has ever sent spam. The article continues,
“We’re interested in hearing CloudFlare’s explanation of how they arrived at the 94% figure and why they choose to block so much legitimate Tor traffic. While we wait to hear from CloudFlare, here’s what we know: 1) CloudFlare uses an IP reputation system to assign scores to IP addresses that generate malicious traffic. In their blog post, they mentioned obtaining data from Project Honey Pot, in addition to their own systems. Project Honey Pot has an IP reputation system that causes IP addresses to be labeled as “malicious” if they ever send spam to a select set of diagnostic machines that are not normally in use. CloudFlare has not described the nature of the IP reputation systems they use in any detail.”
This article raises some interesting points, but also alludes to more universal problems with making sense of any information published online. An epistemology about technology, and many areas of study, is like chasing a moving target. Knowledge about technology is complicated by the relationship between technology and information dissemination. The important questions are what does one know about Tor and how does one know about it?
